Grout restoration pen - Cover stained grout lines in minutes
4.7 / 5.0 (based on more than 2613 reviews)
Cover years of discolored, dingy grout in about 10 minutes
Tired of dull, brownish grout that makes your whole bathroom look old no matter how hard you scrub? This water-based grout pen paints directly over discolored, mold-affected grout lines, making your tiles look like they were just installed — without tearing anything out or hiring a contractor.
Stop scrubbing grout that never really gets clean again
Grout is porous. Once soap residue, oil, and mold soak into the surface, no amount of bleach or scrubbing will get them back out. You can spend an hour on your knees with a toothbrush — and that orange-brown stain still wins.
➤ Covers deep-set stains on the first pass: Run the tip over orange-, brown-, or black-stained grout and watch it disappear under a clean, bright line you actually want to look at.
➤ Built-in anti-mold agents help slow regrowth: The water-based formula contains anti-mold additives that help prevent mold from settling back into the freshly revived grout.
➤ Low odor and non-toxic — safe for home use: No bleach fumes, no harsh solvents. Safe to use in a small bathroom with the door closed, even around children and pets.
Water-based color ink that bonds to porous grout and stays put
The chisel tip applies a thin, opaque pigment that soaks into the porous top layer of your grout and dries quickly, locking in an even color — much like a paint pen seals scratches on metal. Once dry, the finish is water-resistant, so daily showers, splashes, and normal cleaning will not wash it away.
It will not flake or peel like cheap sealers can. With regular cleaning and proper ventilation, the refreshed grout keeps its appearance for months — and when high-traffic areas eventually wear down, you can touch them up in seconds with the same pen.
Why DIYers choose this pen instead of regrouting
Homeowners who have already received quotes of over $400 to regrout a single shower discover that one pen can handle the visible work in an afternoon. They share before-and-after photos of showers, kitchen backsplashes, and floor tiles that look like they were newly tiled — without using a single power tool.
